Changed the behaviour when logging with the screen down in axial mode. Dip direction is now always the down direction. This also affects the cardinal shown in dip & strike axial modes. Note that the symbol always correctly indicated the direction that was being recorded.

Fixed a bug when logging with the screen down in dip & strike normal mode. Previously, when the screen was down the strike did not flip to match what was indicated by the red arrow.

Additionally, the dip direction cardinal letter would indicate the direction 90° anti-clockwise from the strike (when viewed from above). This was 180° opposite to the direction the phone was actually dipping (as indicated by the symbol).

Now, the strike flips correctly to match the red arrow, and the dip direction cardinal letter always indicates the direction 90° clockwise from the strike (when viewed from above).

Fixed the same problem when logging with the screen down in dip & dip direction mode. Previously, when the screen was down the dip direction did not flip to match what was indicated by the vertical line in the red symbol (ie, down), and was instead 180° opposite. Now, the dip direction flips correctly and matches the symbol.

Other changes:

Added the word “Overturned” to the description of overturned records.

Added the option to display coordinates in UTM. Records are still saved in lat/lon, as that is the format given by the GPS.

Rocklogger is now 1 year old! The first version was uploaded to the Android Market (now the ambiguously-titled Play Store) on 14th March 2011. Since then, Rocklogger has been downloaded over 8,000 times! Who would have thought there’d be so many geos with an Android phone?

To celebrate, the Unlocker is now half price in the market/store, for the next 2 weeks! After that, pricing in the different currencies will be adjusted a little to account for changes in the exchange rate over the past year (against the Australian price of AUD$9).

Thankyou to everyone who has contributed bugs and feature requests! I will continue to support and update the app in my spare time, when I’m not at my new job – making apps!

A new update has been posted to the Android Market. This update adds the ability to export KML files for use in the desktop version of Google Earth. A KML file will be generated & attached automatically when ‘Email log’ is selected from the main logging screen. The file will additionally be stored in the /Rocklogger/kml directory.

If the log has associated photos, put the KML and JPGs in the same directory (on your computer) and the photos will be viewable within Google Earth at the associated coordinates.

A new update has been posted to the Market. This update addresses a problem with corrupt log files affecting users in some countries (described here). It also adds a horizontal line to the logging screen, to make it visually easier to log in the same plane as the phone’s scree. Logging like this usually gives more accurate azimuth angles than logging planes at random angles to the phone’s screen.

Added a horizontal white line to the logging screen, to make it visually easier to log in the same plane as the phone’s screen (which is usually more accurate than logging planes at random angles to the phone’s screen)

Fixed a bug where the logfile was corrupted in locales which use , instead of . for decimal points

I recently moved to Germany for a working holiday (software and GPS work for a research institute).

One odd thing I noticed is that in Germany, copyright to the word gmail belongs to some guy who registered the name back in 2000. The effect of this is that gmail is called Google Mail here. What was strange was that the gmail app on my phone changed its name, by itself, to Google Mail.

Back to Rocklogger, and an important lesson in localisation. In Germany and many other European countries, decimal numbers use commas instead of points, eg 5,3 instead of 5.3.
This meant that whenever Rocklogger saved a log on a European-localised phone, extra commas corrupted the CSV tables meaning recorded data couldn’t be used by the stereonet plotter, maps, or anything else.

An update is about to be posted, which replaces occurrences of ,s with .s in number strings.

Note that my Australian phone didn’t change localisation and have this problem, it only renamed gmail.

PS: German users can look forward to a German translation in the coming weeks!

This update was a considerable amount of work, involving much consultation with geologists, and many iterations of the user interface. All up it has involved over a month’s work (part time), which is why it is restricted to paid users only. I hope you find it incredibly useful!

Stereonet plotting. Plot records from log files as poles or planes on a stereonet (paid only)

Filter records by plane type

Each plane type is plotted in a different colour, including user-defined planes

Draw poles or planes on the stereonet by touching or using the sliders. Use this to find intersections of planes or trends of pole clusters

Sensor averaging. Adjust how fast sensor values are updated on screen via the new option in settings
